Following the style of Fig. 2.17 on page 18, make sketch graphs of the x- and y-components of a rotating particle as a function of time for the case where the starting phase < p is:
(a) 0°.
(b) 135°.
(c) In radians.
(d) 3π/2 radians. In each case, comment on the form of your graphs, noting particularly whether they are simple sine or cosine functions.
